This book presents an intensively systematic description and illustration
of 9 fossil groups of Permian, Jurassic and Cretaceous, including fusulinids,
corals, brachiopods, bryozoans, foraminifers, radiolaris, scleractinis,
bivalves, gastropods and plants and amounting to 156 genera and 267 species,
among which are 4 new genera and 62 new species. The feature of each biota,
the biotic successions and the evolution fo biogeographical provinciality
in various period are respectively discussed in detail. A further subdivision
and correlation of the Permian, Jurassic and strata has been summed up.
On the basis of the new achievements of studies and the paleogeographical
evolution of Qinghai-Xizang(Tibet) Plateaus as the east part of Tethy
is briefly elaborated according to the changes of biofacies and sedimentary
facies in different stratigraphical regions and the plate theory.
